Why are cookies needed at all?
Cookies are meant to make the user's visit to the website easier and more user-friendly. For example, with online shopping they enable the website to "remember" on your next visit what products you have in your shopping cart, or to automatically display your preferred layout and font size. However, not all cookies are useful and solely for the user's benefit. For example, tracking cookies are used to follow your behavior on websites and place advertising accordingly, or to make websites more user-friendly. You should accordingly think about which cookies to accept and which to reject. For this decision, it is helpful to know what kinds of cookies there are.
